Abstract Particle-size measurements of some typical loess-soil samples taken in different localities the Chinese Loess Plateau demonstrate that grain size ratio <2 μm/>10 μm (%) can be used as an indicator variations intensity East Asian winter monsoon winds. Grain-size curves Baoji and Weinan sections show this proxy is very sensitive to alterations. Analytical results also suggest during soil-forming periods, eolian dust accumulation was still substantial and, hence, loess deposition...
The evolution of the lunar magnetic field can reveal Moon’s interior structure, thermal history, and surface environment. mid-to-late-stage is poorly constrained, thus, existence a long-lived dynamo remains controversial. Chang’e-5 mission returned heretofore youngest mare basalts from Oceanus Procellarum uniquely positioned at midlatitude. We recovered weak paleointensities ~2 to 4 microtesla basalt clasts 2 billion years ago, attesting longevity until least midstage. This paleomagnetic...
Temperature dependence of magnetic susceptibility (χ−T) has been widely used to determine changes in mineralogy natural samples during heat treatment. We carried out integrated rock experiments interpret the χ−T curves Chinese loess/palaeosols argon. both raw materials and heated samples. In addition, we also investigated properties extracts residues quantify contributions from each fraction bulk properties. For heating curves, loss (∼30 per cent) between ∼300–400 °C is caused by inversion...
The north‐striking Tancheng‐Lujiang (Tan‐Lu) fault is a conspicuous and controversial feature of the eastern Asian landscape. Near southeast extremity in Anhui Province, we collected paleomagnetic samples at 17 Middle Triassic (T2) 10 Upper Cretaceous (K2) to lower Cenozoic (E1) sites. T2 remanent magnetizations are interpreted as primary two three areas. areas rotated 37° 137° counterclockwise with respect South China Block (SCB) reference direction. K2‐E1 magnetization directions pass...
The timing of the Jiufotang Formation remains speculative despite recent progress in study Jehol Biota. In this paper we contribute to topic with 40 Ar/ 39 Ar dating on K‐feldspar (sanidine and orthoclase) from tuffs interbedded within fossil‐bearing shales Formation, upper part Group Chaoyang, Liaoning, northeastern China. step heating analyses SHRIMP U‐Pb zircon data indicate that at Shangheshou section erupted 120.3 ± 0.7 million years ago. This result confirms an Aptian age for was...
We have conducted a multiparameter investigation of 15 loess‐paleosol couplets (S0/L1 to S14/L15) from the Jiaodao section in central loess plateau China using environmental magnetic approaches coupled with soil science techniques. The parameters display systematic variations that seem be closely related paleoclimate and intensity pedogenesis. High‐temperature susceptibility curves paleosols show generally decreasing trend reversibility base Lishi Formation Holocene black loam, possibly...
To retrieve reliable long‐term paleoclimatic signals from the Chinese loess/paleosol sequences deposited over past 2.6 Myr, multiparameter mineral magnetic investigations have been conducted on Jiaodao section central Loess Plateau. First, lithogenic components and pedogenic overprinting were chemically separated by citrate‐bicarbonate‐dithionite (CBD) method. The properties of least pedogenically altered loess units post‐CBD loess/paleosols are dominated coarse‐grained magnetite. Increasing...
Quaternary glacial/interglacial cycles have been imprinted on the Chinese loess/paleosol sequences through pedogenesis. In order to accurately decode paleoclimatic signals carried by these pedogenic particles it is essential quantify pedogenically produced magnetic in terms of mineralogy as well grain size distribution (GSD). To date, GSD has not determined because dearth available means for analyzing extremely fine grained (nanometer‐scale) particles. Using low‐temperature techniques, we...
